To allwhom it mayconcern:

B e it known thatI,` LBERT P. Cnam., a citizen ,o the United States, residing lat Ionia, in'the county of Kent and State of `5.Mich1gan, have invented certain new and useful Improvements in Reversing Mech-4 anism, of which the following is a specification.

reversing mechanism, and its object is to provide a neat, com expensiv'eand 'noise ess reversing mechamsm for .use upon washing 4machines and Akindred l machines where areversing device is desir-- loable; vattain thiszobject by the mechanism v.Figure 1` is a side elevation of, the device.

Figli 2 is an edgeelevation. Fig. 3 is a topV plan lof Fi 1', with alll parts in place.l Fi'gl .large-gear. w eel'and sprocket wheel removed plai.r 1ly-y show the reversing `mechanism.' Fig. 5y isla backelevationpf the Zratchet 4wheel, and its actuating -levers &c.

4F;ig.. 6 shows the. manner of inserting a washfin machine'=shaft. Fig. 7 shows end-views Ao .---thevshaftand bearings-that support the machine shaft. Fig. 81's a side view of av l ratchet wheel showing a grooved cam to use in lieuof the side lugsshown in Fig. 1.

`Similar letters Fre fer to similarparts throughout the several views.

' This reversing mechanism consists =of` abase A which supports the shafts E, H, and

"`F. H is the main driving shaft and has, loosely mountedupon it, a small gear wheel Band a small sprocket WheelC, and between these wheels is a clutch K, also mount- 40 ed upon the shaft H, thatis, so mounted that it 'must revolve with the shaft, but longitudinally adjustable thereon so that .when

thrown to the right. in Fig. 2, downward on Figs. 3 and 4, the lug ethereon will engage l.

the lug b` on the gear wheel B and cause the' gear wheel to revolve with the shaft H, vand if the clutch K is thrownl over to theleft, as shown in Fig. 2,- equivalent to being raised upward in Figs. 3 and 4 the lug lo', on vthe clutch, will engagel the lug o on the sprocket wheel Cand cause thewheel to revolve with` the shaft H. Y The shaft E carries' a large sprocket wheel C that is connected. with the .small sprocket .55 wheel C by a sprocket chain D, so 4that the My invention relates-to improvements ini act, and. practically insprocket Wheel C, when driven by the sprocket .wheel C must revolve the same direction .that the shaft H is revolving.

The shaftEalso carries a large gear wheel B that meshes directly with the small gear Wheel B so that when the clutch K engages the gear Vwheel B the shaft Emust revolve in a direction opposite to that in which the gear Wheel B andthe shaft H is revolving, thus, by the alternate engagement of the gear wheel Band the sprocketl wheel C by theclutchK the shaft E will be made to revolvegalternately, first to the right and -then to the left, with the shaft always .revolving in one direction. 70- 'illustra'tedin the accompanying drawing in My appliance for slidng the clutch K lengthwise of the shaft H to alternately engage the'gear wheel B and the sprocket :wheel C consists of a ratshet wheel. F -mountedto revolve freely 4on the shaft or 4 isan en ar ement of thesame withthe post F- andv having a lu f on' one side,

an'd a lug l. on the other slde diametrically;y Aopposite t e lug f. Thisratchet wheel is gmade"to. revolve, intermittently, byfmean's -of' a awl `g pivotally mounted on the iarm F" w ich,in turn, isinounted on theshaft or post F," and is' r'nade to oscillatebymeans of the eccentric arm G lpivoted at one end to the arm F and the other 'end engaging the eccentric G on the shaft H so that every revolution of the shaft H will cause the ratchet wheel -F to revolve a short distance where it will be held by thepawl g1 until again moved by the eccentric G', as 4hereinbeifore stated. 'I vthen mount a lever I, having lforks I at one end, upon a supporting pin in position so that the body`""o f the lever will engage a roove in the periphery of the clutch K an the forks I will 'stand one each-side of the ratchet wheel so that as the 'ratchet wheel is made to revolve the lug f will throw the lever to position to cause the lclutch to engage the sprocket wheel C during one-half of the revolution of the ratchet 'Wheel F and the lug j" will engage 1.90

natelyengaging i the gear wheel B and105 the sprocket Wheel C', as and with the rel sultsv hereinbefore mentioned. I hold the back end of the lever I to place so that -it mayv readily adjusted to' follow the direetiongiven the forked end I', by means 119" `of alight flexible spring J, mounted upon a post j, as indicated inthe first four figures ofthe drawing.

In Fig. 6 I have shown a very available means for coupling in and support-ing the shaft L that is supposed to support the mechanism to be driven and reversed by the reversing mechanism, which consists of a socket E integral with the shaft E and so 1 0 constructed that the square end of the shaft\ Lmay be'plaeed therein andslid endwise into thejcomple'ted socket, as'indicated by its dotted lines, and the opposite end of the shaft, `marked L, may be supported in the bea-ring M'in which a step m isformed .so that this end of the shaft may be raised a little andI the shaft drawn endwise out of the socket E and easily removed.

In Fig.'8 I h ave shown the ratchet Wheel F With an extended cylindrical4 body having an irregular` groove f in its periphery showing how this construction may bc used .in lieu of the lugs shown in Figs. l, 2, 3 and gi, by placing a roller I -upon the lever I, instead of the forks I.
